Maintain your TTR030C100A2 central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The TTR030C100A2 is a two-and-a-half-ton R-22 residential outdoor condensing unit using R-22 refrigerant. The TTR030 designation identifies a Trane two-and-a-half-ton R-22 commercial condensing unit. Trane and American Standard are sister brands with interchangeable service components at the same configuration. The dual run capacitor, contactor, and outdoor fan motor account for the vast majority of service calls. Repair Clinic stocks genuine Trane OEM parts for the TTR030C100A2 including the Trane capacitor parts, Trane contactor parts, Trane fan motor parts, and Trane high-pressure switch parts.

TTR030C100A2: Two-And-A-Half-Ton R-22 Outdoor Condensing Unit Service
Annual capacitance testing of the dual run capacitor before the cooling season is the most cost-effective preventive maintenance step for the TTR030C100A2. Match all microfarad values from the installed capacitor label before ordering a replacement. The central air conditioner repair help section covers capacitor testing and contactor diagnosis for this platform.
Most Replaced Parts on the TTR030C100A2
Dual Run Capacitor for the TTR030C100A2
The dual run capacitor provides starting and running torque for both the compressor and outdoor fan motor. A reading more than 10% below the rated value causes the compressor to hard-start. Match all three microfarad values from the installed capacitor label before ordering.
TTR030C100A2 Contactor
The contactor closes the 240-volt compressor circuit at every cooling cycle start. Pitted or burned contacts generate heat that transfers to the compressor motor terminals. Replace a contactor with visibly eroded contacts before compressor winding damage occurs.
Outdoor Fan Motor for the TTR030C100A2
The outdoor fan motor pulls air through the condenser coil. Test the run capacitor before ordering a replacement motor, as a failed capacitor produces identical slow-start symptoms at a fraction of the motor replacement cost.
High-Pressure Switch for the TTR030C100A2
A high-pressure switch that trips repeatedly under normal ambient conditions points to a blocked condenser coil, failed fan motor, or refrigerant overcharge rather than a failed switch diaphragm.

TTR030C100A2 Parts FAQ
What is the TTR030C100A2 and what ton size is it?
The TTR030C100A2 is a two-and-a-half-ton R-22 residential outdoor condensing unit using R-22 refrigerant. The TTR030 designation identifies a Trane two-and-a-half-ton R-22 commercial condensing unit. Trane and American Standard are sister brands with interchangeable service components at the same configuration.
Why does my TTR030C100A2 hum but not start?
A unit that hums but does not start has most commonly failed at the dual run capacitor. Test the capacitor with a digital capacitance meter before testing any other component.
What refrigerant does the Trane TTR030C100A2 use?
The TTR030C100A2 uses R-22 refrigerant. R-22 is no longer produced for new equipment and requires EPA 608 certified technicians for any refrigerant circuit service using reclaimed R-22 supplies.
How often should I test the capacitor on the TTR030C100A2?
Test the capacitor annually before the cooling season. A reading more than 10% below the rated microfarad value indicates a weakening capacitor that should be replaced before it fails under peak summer load.
